[Anomalous origin of the right pulmonary artery from the ascending aorta associated with aortopulmonary window].

Anomalous origin of one pulmonary artery from the aorta is rare. We report a case of a three-month-old infant with aortopulmonary window and anomalous origin of the right pulmonary artery from the ascending aorta. He underwent surgery with anastomosis of the right pulmonary artery, ligation of the aortopulmonary window and the patent duct.

[Prognostic factors associated with postoperative morbidity in children with isolated ventricular septal defect].

Background: Isolated ventricular septal defect (VSD) is one of the most common congenital heart diseases worldwide. Prognostic factors associated with postoperative morbidity in patients with isolated VSD in the Hospital de Pediatría del Centro Médico Nacional Siglo XXI have not been identified.

Methods: A retrospective cohort study was conducted from January 1, 2009 to December 31, 2013.

[Mortality-associated factors in pediatric patients with Blalock-Taussig shunt].

Background: Congenital heart disease with decreased pulmonary flow survival has increased due to systemic pulmonary fistulae (SPF); nevertheless, complications may occur. The purpose of this study was to identify mortality-related surgical and biochemical factors in pediatric patients with modified Blalock-Taussig shunt.

Methods: A cohort was formed with congenital heart disease newborns who survived Blalock-Taussig-type palliative systemic pulmonary fistulae surgery.

Endoscopy for the initial suspicion of vascular rings in tracheoesophageal compressions: correlation with surgical findings.

Unlabelled: Vascular rings (VR) may produce extrinsic compression of trachea and/or esophagus. Diagnosis relies on nonspecific clinical data from resulting compression and image studies, mainly angiography, computed tomography, and cardiovascular MRI. Because of their low incidence, diagnosis is often missed.

[Transcatheter occlusion of the patent ductus arteriosus with detachable coils: immediate results and intermediate-term follow-up].

Objective: To determine the success rate and safety of percutaneous closure of patent ductus arteriosus (PDA) with a detachable coil.

Methods: Forty-one children with small- to moderate-size PDA (maximum diameter < or = 4 mm) underwent percutaneous coil occlusion. The results were assessed by angiography and echocardiography.
